Abstract

The embodiment of the present invention discloses a method and a device for online detection of the accuracy of the charging amount of the charging pile. The method obtains the charging amount measured by the target charging pile online during the charging process of the target charging pile to the standard vehicle or the calibration vehicle. The third calibration coefficient of the target charging pile is calculated from the charging amount and the first calibration coefficient or the second calibration coefficient. Whether the charging amount measured by the target charging pile is accurate is judged by the coefficient average value and coefficient variance of the third calibration coefficient. The method uses the charging amount detected during the use of the charging pile to judge the accuracy of the charging capacity measurement, and the judgment result truly reflects the accuracy of the charging capacity measurement during the use process of the charging pile, and ensures that the maintenance of the charging pile can be improved. The accuracy of the charging capacity measurement during the use of the charging pile. On the other hand, this detection method of obtaining the charging amount of the charging pile online does not need to test the accuracy of the measurement of the charging pile one by one, and the detection efficiency is high.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of equipment supervision, and in particular to a method and device for online detection of the charging accuracy of charging piles. Background technique [0002] The use of electric energy inevitably involves trade settlement, and how to ensure the fairness and justice of electric energy measurement has become an important prerequisite. For the accuracy of the charging amount reported by the charging pile, use professional instruments for offline measurement at the legal metering institution, that is, connect the professional instrument to the charging pile, simulate the charging process or use a real car to charge, and check the charging amount reported by the charging pile and the professional instrument to detect the power error between. Charging equipment operators will also pay attention to the accuracy of the charging amount. If the actual charging amount is greater than the ...
